Overview
Registered in 1999, *Hosta* 'Rosedale Dough Boy' is a large, upright cultivar derived from a cross between *H. ventricosa* and *H.* 'Invincible'. It is visually distinctive for its broad, blue-green leaves with heavy, medium-green rippled margins, a dull upper surface, and a glaucous bloom beneath.
In the Garden
'Rosedale Dough Boy' reaches a mature spread of approximately 32 inches (81.3 cm) and a height of 19 inches (48.3 cm), with scapes rising 24 to 27 inches (61.0 to 68.6 cm). It performs best in partial to full shade, typical for blue-leaved hostas, where its glaucous bloom is preserved. Its substantial size and upright habit make it suitable as a specimen or in mixed shade borders alongside ferns, heucheras, and other large hostas.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as growth emerges. As with most hostas, slug and deer damage may occur; monitor leaves for feeding signs and manage accordingly.
